Climate Controls
Climate Control System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
If your vehicle has the remote start feature and it is
activated, the climate control system will automatically
cool the vehicle if the temperature is greater than
90°F (32°C) and heat the vehicle if the temperature is
below 37°F (3°C). If the temperature is between
37°F (3°C) and 90°F (32°C), the last control setting
selected when the engine was running will be used.
Normal operation and the last setting of the climate
control system will return after the ignition key is turned
to the C (RUN) position. SeeRemote Keyless Entry
System Operation on page 2-6for more information.
Operation
(
(Off):Turn the left knob to this position to turn the
climate control system off.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan speed will be temporarily reduced between
the transition to a new mode. The fan will resume when
the new mode is complete.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
Temperature Control:Turn the center knob clockwise
or counterclockwise to warm or cool the air coming
through the outlets.
Use the right knob to select from the following modes:
H(Vent):This mode directs outside air to the
instrument panel outlets. If driving in city traffic, and the
vehicle is stopped and idling, or the weather is hot,
turn on the recirculation mode.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to
the oor outlets. Slightly cooler air is directed to the
instrument panel outlets and warmer air is directed to
the oor outlets.
3-23

After your vehicle is started, the display will show the
interior temperature settings.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.
AUTO
#(Automatic Air Conditioning):If the
AUTO position is selected on the fan or mode control,
the system will automatically control the air conditioning
compressor. The A/C compressor will run automatically
even at cool outside temperatures in order to
dehumidify the air. The A/C indicator light will be lit
when the system is operating automatically, even
at near freezing outside temperatures. Press the
A/C button on the fan control to turn off the A/C.
For improved window clearing performance in defog or
defrost modes, the A/C compressor will run
automatically in damp cool conditions.
h(Auto Recirculation):If the AUTO position is
selected on either the fan or mode control, the system
will automatically control the air inlet to supply fresh
outside air or recirculate the interior air to cool the car
faster. The indicator light on the recirculation button
will light whenever the system switches to recirculation.
You may force outside air by pressing the button
when the light is lit. The next time AUTO fan or mode is
selected, the air inlet will reset back to AUTO operation.
Manual Operation
9(Fan):Turn the left knob either to the left or right to
adjust the fan speed. Turning this control completely
counterclockwise will turn on the automatic fan operation.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
9(Off):Turn the left control to this position to turn the
entire climate control system off.
To change the current mode, select one of the following
positions using the right control:
F(Vent):Turn the control to this mode to direct air to
the instrument panel outlets.
*(Bi-Level):Turn the control to this mode to direct
approximately half of the air to the instrument panel
outlets and most of the remaining air to the oor outlets.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
3-27

Outlet Adjustment
Use the levers located in the middle of the front outlets
to change the direction of the airow and use the
shutoff wheels to adjust the amount of airow.
You can adjust the rear seat outlet direction of the
airow using the lever in the center of each outlet.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/lter, it may need to
be changed periodically. For how often to change the
passenger compartment air lter, seeScheduled
Maintenance on page 6-4.
The access panel for the passenger compartment air
lter is located under the hood near the windshield,
on the passenger’s side of the vehicle.

If the ENGINE OIL LOW ADD OIL message appears in
the Driver Information Center (DIC), it means you
need to check your engine oil level right away. For more
information, seeDIC Warnings and Messages on
page 3-56.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

How to Reset the Engine Oil
Life System
The Engine Oil Life System calculates when to change
your engine oil and lter based on vehicle use.
Anytime your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE ENGINE OIL SOON message being
turned on, reset the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Engine
Oil Life System, do the following:
1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC
for more than ve seconds. The oil life will change
to 100%.
If the CHANGE ENGINE OIL SOON message comes
back on when you start your vehicle, the Engine Oil Life
System has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a goodhand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
lter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of used oil, ask your
dealer, a service station, or a local recycling center
for help.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-12for
the location of the engine air cleaner/lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change after each
50,000 mile (83 000 km) interval. SeeScheduled
Maintenance on page 6-4for more information. If you
are driving in dusty/dirty conditions, inspect the lter
at each engine oil change.
